CLUSCTL_CLUSTER_UNKNOWN control code

This control code verifies that control codes are being processed on the node where execution of the control is directed. Applications use this control code as a ClusterControl parameter.



ClusterControl( 
  hCluster,                 // cluster handle
  hHostNode,                // optional node handle
  CLUSCTL_CLUSTER_UNKNOWN,  // this control code
  NULL,                     // input buffer (not used)
  0,                        // input buffer size (not used)
  NULL,                     // output buffer (not used)
  0,                        // output buffer size (not used)
  NULL                      // resulting data size (not used)
);
